The side walls 36 have window openings 31, and the transversely archedroof 38 has large curved windows 39 in its longitudinal sides and endwindows or Windshields 40 in its ends.

The roof end portions 4|, between windows 40 and end walls I 8, are ofnormal height and curvature so as to lineup and blend in with cars ofstandard single-deck construction. The longitudinal central portion ofthe roof is formed as a duct 42 for air, wiring, lights, etc.

The compartments 29 over the truck locations are, of course, providedwith access doors or hatches and, if desired, with windows. Theseoptional features are not shown save for the louvers or vents 43 inFigs. 1, 2, and 3 to 5.

The constructional details of the new design may follow in large partthe construction disclosed in copending application Railway Car, SerialNo. 734,955, filed March 15, 1947, by inventors Walter B. Dean andAlbert G. Dean, issued on March 18, 1952, under Patent No. 2,589,997.

A car according to the invention is, of course, more expensive than anordinary coach car or a car with a short-length dome, as disclosed inthe aforesaid application. In the final analysis, however, the expensefor a train equipped with the new cars is about within the same range asthe expense'for a train composed of ordinary cars and a number ofshort-length dome cars.

Then-new design presents additional advantages.

Firstly-For the short-length dome car, it was found desirable tomaintain a certain ratio between non-revenue dome seats and seats at thenormal level. In cars of the new design all seats at the high level may,of course, be revenue seats or a much smaller number of these dome carsmay be used for a train of a certain length mainly composed of ordinarycars.

Secondly.-Al1 dome or double-deck cars have the advantage that they giveon the upper deck much quieter riding to the passengers becausenoticeable advantage becomes available to a much greater number ofpassengers in a car of g the new design than in trains with a relativelysmall number of dome seats as afiorded by the short-length dome carsinterspersed in a majority of regular cars.

The invention is susceptible to modifications and adaptations withoutdeparting from its basic concept. For instance, the side aisles may belowered one step with respect to the main portion of the floor above thetrucks, in which case, the side aisles would be connected by a 2151516step with the floor of the respective vesti- What is claimed is:

1. A railway car of cross-sectional dimensions keeping substantiallywithin established clearance lines, comprising: end walls; side walls; aroof; normal-level floors, at about the fioor level of customarysingle-deck passenger cars, in

and adjacent the location of trucks for supporting the car; vestibulesat the ends of the car provided with passage doors of standard heightand dimensions in said end walls; a compartment with a low-level floorbetween said truck locations at a level below said normal-level fioors;a high-level floor extending substantially over the full length of thecar from the vestibule at the one end to the vestibule at the other endthereof, said high-level floor being at full standing height above saidlow-level floor, at less than standing height above said normal-levelfloors, and at full standing height below said roof; transversepartition walls interconnecting said side walls, said low-level floorand said highlevel fioor in the meeting regions of said normallevelfloors and said low-level floor; longitudinal partitions spaced from oneof said side walls and extending between said normal-level floors andsaid high-level floor and providing side aisles I communicating withsaid vestibules and the com- 30 partment with the low-level floor, saidside aisles projecting upwardly beyond the high-level floor by upwardextensions of their longitudinal par-' tition walls and by raisedceilings so as to provide full standing height in the side aisles; stepsconnecting said side aisles with said low-level floor; at least oneentrance door in one of the side walls such as at the location of one ofsaid vestibules; and at least one stair leading to said high-levelfloor.

2. A railway car of cross-sectional dimensions keeping substantiallywithin established clearance lines, comprising: end walls provided withpassage doors of standard height and dimensions as to permitcommunication with adjoining ordinary single-deck cars; side walls; aroof; end floors, in and adjacent the location of trucks for supportingthe car, at a level sufiicient for clearing such trucks; vestibules atthe ends of the car in communication with said passage doors; acompartment with a low-level floor between said truck locations at alevel below said end floors; a high-level floor overlying said lowlevelfioor and extending therebeyond in the 1ongitudinal direction of thecar, said high-level floor being at full standing height above saidlow-level floor but less than standing height above said end floors;transverse partition walls interconnecting said side walls, saidlowlevel floor and said high-level floor in the meeting regions of saidend floors and said low-level floor; longitudinal partitions spaced fromone of said side walls and extending between said end floors and saidhigh-level floor and providing side aisles communicating with saidvestibules and the compartment with the low-level floor; said sideaisles having projections extending upwardly beyond the high-level floorto full standing height; steps connecting said side aisles with saidlow-level floor; and at least one stair connecting one of said low-leveland end floors with said high-level floor.

3.
